Frequently Asked Questions

Q: What size batteries fit in this 18650 battery case holder?

A: This battery case holder is specifically designed for standard 18650 Li-ion cylindrical cells (18 mm diameter × 65 mm length). It does not fit AA, AAA, or other battery sizes.

Q: What is the difference between the 2-slot and 3-slot configurations?

A: The 2-slot holder connects batteries in a parallel circuit, which keeps voltage the same as a single cell while doubling the capacity (mAh). The 3-slot holder connects batteries in a series circuit, stacking the voltage output of each cell — ideal when your project requires higher voltage.

Q: Can I use this battery case for Arduino or other maker board projects?

A: Yes! This 18650 battery holder is a popular choice for Arduino, Raspberry Pi accessories, LED drivers, and other DIY maker board builds that require a compact, reliable 3.7V (or higher, in series) power source.
